JACQUARD EMBROIDERY-MACHINE.

spcincation of Letters Patent.

Patented Oct 8, 1912.

Application led October 2, 1911. vSerial No` 652,312.

To all whom 'it may concern:

Be it known that. I, ROBERT ZAHN, a subject of the King of Bavaria, residing at Plauen, Vogtland, in the Kingdom of Saxony, Germany, have invented certain new and useful Improvements in Jacquard Embroidery-Machines, of which the followingis a specification. i,

The present invention pertains to jacquard emhroiderinfb machines, in which a plurality of rows of needles having d'ilerently colored threads are automatically and alternately operated to produce a variegatedfdesign.

My invention is illustrated in the accompanying drawing, in which similar reference letters denote corresponding parts and in which- Figure 1 is a diagrammatic elevation Vof the machine and Fig. 2 is a plan view of the needle rows.

.ln the drawing, which forms a part of my invention, l, and 2 denote the needles of two dilferent rows. There may be, however, any number or' needle rows. The needles ot' the various rows are threaded with differently colored threads t and are operated from a cam 3 or othcr'suitable means in well known manner.

The followingmeans is used for the transmission o'f motion from the cam 3 to the needle rows. A vertical bar 6 carries su erposed rolls 4l and 5 which are adapte to travel on an outer and an inner edge `formed on the cam 3. This bar has a parallel guide consistingl of pivoted arms 7 and 8, 8. The arm 8, 8 is a part of a double armed lever, the arm 8 of which carries a coupling rod 10. The lower end 11 of the latter is adapted to alternately engage notches 12 and 12 formed in the rods 13 and 14 respectively which by angular levers 19 and 20 are positively connected to the needles 1 and 2 respectively. The alternate coupling of the rod '10 to the rods 153 and 14 is effected automatically by the jacquard card of the jacquard mechanism, which is of well known construction and in the drawing,r is denoted by the box 15. The jacquard mechanism operates the rod 16 which by an angular lever 17 and rod 18 is connected tothe rod l0, so that by the movement of the rod 1U the rod 10 is caused to alternately engage the notches 1Q, 12. Thus, when the har (3 by the rod l() is coupled to rod 13, the needles l ofone row will be operated and when the bar 6 is coupled to rod 1-1 the needles 2 of another row will be o ierated.- In this man ner, it is possible to o tain a variegated embroidery design.

What I claim and desire to secure by Letters Patent is: Y

1. In jacquard embroidering machines, a jacquard mechanism, a pluralit of rows of needles adapted to carry threa of different color, and means whereby the needles of the different rows are alternately controlled by said jacquard mechanism.

2. In jacquard embroidering machines, a jacquard mechanism, a plurality of rows of needles adapted to carry thread of different color, motion transrrtting means, and means controlled by saidjacquardfmechanism and ada ted to alternately eouplethe needles of the diterent rowsto the'sald motion transmitting means. ,y

3. In jacquard embroidering machines, a jacquard mechanism, a plurallt of rows of needles adapted to carry ythrea of-diljerent color, driven means, motion transmlttma means for the needles of each row, -a coupling means between saidrst named means andthe latter means, and means controlled by said jacquard mechanism and operatively connected to said coupling means to effect an alternate coupling of the driven means with the motion transmitting meansof the rlill'erent needle rows. l

In testimony whereof I alixA my signature in presence of two witnesses. 1 ROBERT ZAHN.
